Well, apples are red.
Actually, I had 3 cases, and my original plan was to get each one refinished in a different color: black, blue, and red. The black one got messed up, so I had the 2nd one done in black as well, and had the 3rd one done in red. It turns out the red one looked the best, so that's the one I did the full mod on. I have one of the black cases (unmodded) listed on eBay too. I just haven't gotten around to posting it here.
The black one looks nice, but it's such a plain color. The red one, OTOH, looks stunning.
Unfortunately, I didn't get the tray until after I got the case refinished, and it would have been too cost prohibitive to get just the back panel anodized in red since I had to get it professionally refinished, as I don't have any DIY anodizing equipment. It would be pretty easy to remove the back panel to get it refinished if you happen to know a cheap electroplating shop or have your own DIY equipment.

I have this case listed on eBay, but I thought I'd post it here too. You will receive the following:
Modded PowerMac G5 case, anodized in red
ATX motherboard tray from Mountain Mods (installed)
600W Corsair CX600 power supply unit (installed)
2 x 80mm case fans (installed) (If you need additional fans, the case has room, but you may need to do some additional modding yourself.)
HDD/SSD tool-less dock--holds up to 1 HDD and 2 SSDs (not included)
Front panel to ATX I/O cable (made by AlohaCab)
Original Plexiglas shield
I put a lot of money and time into this project, and I'm just looking to get back my costs plus a little extra for the countless hours I spent on it. I'm asking $420 OBO + actual shipping costs.
All the hard work of modding the case has already been done, and it's ready for assembly.
Let me know if you have any questions.
